Abstract

PURPOSE: To prepare the title composition having excellent crystallinity and releasability, and useful as a molding compound, by compounding a polyester composed mainly of polyethylene terephthalate with a specific epoxy compound and a polyester elastomer.
CONSTITUTION: A polyester wherein the content of ethylene terephthalate unit is ≥80%, is compounded with (A) 0.1W15wt% of an epoxy compound having a polyoxyalkylene unit and at least one epoxy group in one molecule, pref. a polyalkylene glycol glycidyl ehter having a molecular weight of 200W1,500, (B) 0.2W 20wt% of a polyester elastomer having a glass transition temperature of ≤10°C, pref. a polyalkylene terephthalate/polytetramethylene glycol block copolymer, and pref. (C) an inorganic filler such as glass fiber, and a releasing agent such as the ester of a 15W50C fatty acid and an alcohol.
